Canadian 24-Hour Movement Guidelines for the Early Years: Please Complete This Brief Survey

| March 24, 2017 | 0 Comments

As a childcare provider, practitioner or researcher whose work is in some way connected with physical activity, sedentary time and/or sleep, you are being invited to participate in a survey soliciting your opinion on a draft of the Canadian 24-Hour Movement Guidelines for the Early Years: An Integration of Physical Activity, Sedentary Behaviour, and Sleep (herein referred to as the 24-Hour Guidelines). Please note that this is different from the survey you may have received last year in relation to new guidelines for children and youth.

With leadership from the Canadian Society for Exercise Physiology, a group of Canadian and International research and practice experts in physical activity, sedentary behaviour, sleep, and health promotion met to develop the 24-Hour Guidelines. After reviewing and consolidating the evidence, the experts have produced an initial version of the 24-Hour Guidelines.

One of the final stages in the development of the 24-Hour Guidelines is to gain feedback about the clarity of the guidelines, as well as level of agreement, perceived importance, applicability, feasibility, resource implications, and equity. Acceptance and dissemination of the 24-Hour Guidelines is important for the alignment of strategic efforts in policy, practice, and research aimed at promoting health for Canadian infants, toddlers and preschoolers.

PhD Opportunity

| March 7, 2017 | 0 Comments

A PhD opportunity is available at Glasgow Caledonian University.  The general description is below.  For more details, please fill out the contact details here.

Project Description

Glasgow Caledonian University and Biomathematics and Statistics Scotland present an exciting PhD opportunity to work at the cutting edge of public health science, developing new statistical techniques and applying them to large datasets addressing a global health issue.

Background
Lifestyle behaviours throughout the day and physical activity have a significant impact on health and healthy ageing. Public health and clinical interventions seek to modify these behaviours to prevent and manage chronic disease and promote healthy independent ageing. As time is limited throughout the day, time spent in each behaviour necessarily impacts time spent in the others. Nowadays it is possible to record high volumes of high-precision continuous behavioural data thanks to modern body worn sensor and mobile health technologies. However, one key issue is dealing with them consistently and using them to understand the dynamics of the interplay between behaviours and how it can affect the effectiveness of interventions. Current conceptual and analytical approaches in physical activity epidemiology essentially consider lifestyle behaviours as isolated actions, ignoring the interplay between them and the intrinsic multivariate relative nature of the data generated. The introduction of compositional analysis for relative data in physical activity research was recently pioneered by a collaboration between GCU and BioSS as a major paradigm shift and progress.

Aims
This PhD project will focus on developing, implementing and applying compositional methodology for the analysis of longitudinal and randomised control trials to inform public health interventions targeting lifestyle behaviour synergistically. The first year will focus on familiarisation with the technical fundamentals, the application field and the development of models and methods. In the second year these methods will be implemented, put to the test, contrasted and refined using real data to study the life course determinants and the effects on health and healthy ageing of the dynamics of physical activity behaviours. The third year will be devoted to complete scientific publications, elaborate guidance to inform intervention and public health policy about the most effective ways to gain health benefits when targeting multiple lifestyle behaviour synergistically and thesis writing.

Specific requirements of the project:
– Degree or Master in a quantitative discipline (statistics, mathematics or related are preferable).
– Demonstrable training in multivariate data analysis and models for longitudinal data would be advantageous. Familiarity with compositional data analysis methods would be valuable.
– Previous experience with at least one programming language and statistical programming experience using R would be desirable.
– Experience in research would be desirable.
– Experience in dealing with health and physical activity data would be desirable.
– Keen interest in developing a research career in the interface between quantitative sciences and scientific applications, and acquiring widely transferable skills.
– Interest and ability to work in a multidisciplinary team.

Helping older adults become more active: the SITLESS study

| October 11, 2016 | 1 Comment

Today’s post comes from Dr Mark Tully, and describes the SITLESS study.  You can find more about the study at http://sitless.eu/.

The SITLESS study is an EU-funded Horizon 2020 project being conducted in collaboration between seven institutions based in Europe, including; Fundacio Salut I Envelliment / FSIE (Spain), Blanquerna Foundation (Spain), University of Southern Denmark (Denmark), Queen’s University Belfast (UK), Ulm University (Germany), University of Glasgow (UK) and Siel Bleu (France). The primary aim of the SITless study is to assess the long-term effectiveness and cost-effectiveness (18 ­month follow-up) of a complex behavioural intervention on sedentary behaviour and physical activity in an inactive, community dwelling, older adult population based on existing exercise referral schemes (ERS) enhanced by self-management strategies (SMS).

Individuals aged 65 years and over who live in community settings, who are able to walk independently with or without an aid, who have a low physical activity level (insufficiently active to meet the current physical activity guidelines), who do not have uncontrolled disease and who are otherwise deemed suitable to take part in the exercise referral scheme by their healthcare professional will be recruited.

The study will include four assessment periods at baseline, post-intervention, 12-months and 18-months post-intervention. Participants will complete a variety of questionnaires and simple tests to assess their ability to complete certain everyday activities such as balancing, sit-to-stand and walking ability. Participants will also wear an ActiGraph activity monitor for seven days to measure their daily activity levels.

Participants will be randomised to either:

  • ERS+SMS group: An exercise programme combined with seven additional sessions lasting up to 17 weeks in total as well as four telephone calls. These will mainly be group-based sessions to help support individuals to sit less and be more active.
  • ERS group: Same intervention as above without receiving any additional sessions lasting for up to 16 weeks.
  • Control group: Receive general healthy lifestyle advice for older adults.

The study is starting to recruit participants in October 2016. If you would like to receive more information about the study, please visit the following websites: http://sitless.eu/ and https://clinicaltrials.gov/ct2/show/NCT02629666.

American Heart Association Releases Science Advisory on Sedentary Behaviour

| September 12, 2016 | 0 Comments

The American Heart Association has released a Science Advisory on Sedentary Behaviour and health.  The abstract is available below.  The full paper is available here.

Epidemiological evidence is accumulating that indicates greater time spent in sedentary behavior is associated with all-cause and cardiovascular morbidity and mortality in adults such that some countries have disseminated broad guidelines that recommend minimizing sedentary behaviors. Research examining the possible deleterious consequences of excess sedentary behavior is rapidly evolving, with the epidemiology-based literature ahead of potential biological mechanisms that might explain the observed associations. This American Heart Association science advisory reviews the current evidence on sedentary behavior in terms of assessment methods, population prevalence, determinants, associations with cardiovascular disease incidence and mortality, potential underlying mechanisms, and interventions. Recommendations for future research on this emerging cardiovascular health topic are included. Further evidence is required to better inform public health interventions and future quantitative guidelines on sedentary behavior and cardiovascular health outcomes.

Systematic Review of Childhood Sedentary Behavior Questionnaires: What do We Know and What is Next?

| September 6, 2016 | 0 Comments

A new systematic review in Sports Medicine has been published on sedentary behaviour questionnaires for children. A brief author summary is found below. A full copy of the paper is available for free via the journal Sports Medicine.

This systematic review provides a summary of studies examining the measurement properties of self-report or proxy-report questionnaires assessing sedentary behavior in children and adolescents. In addition, an overview of the characteristics of the included questionnaires is provided. We performed systematic searches in three online databases: PubMed, EMBASE and SPORTDiscus. Studies had to report on at least one of the measurement properties of a self- or proxy-report questionnaire assessing sedentary behavior in a general population under the age of 18 years. Eventually, our searches resulted in 46 relevant studies on 46 questionnaires. Unfortunately, none of the included questionnaires was considered both valid and reliable, due to the lack of attention for content validity and methodological limitations of the included studies. Therefore, we recommend researchers to adopt standardized tools for the evaluation of measurement properties to improve the methodological quality of future studies and we emphasize the importance of assessing content validity.

Canada releases world’s first 24-hour movement behaviour guidelines

| June 17, 2016 | 0 Comments

On June 26 Canada released the Canadian 24 Hour Movement Guidelines for Children and Youth.  These guidelines call for at least 60 minutes per day of moderate to vigorous physical activity, no more than two hours a day of recreational screen time, limited sitting for extended periods and at least 9-11 hours of sleep per night for children 5-13 years, and 8-10 hours for those aged 14-17 years. They were developed by the Canadian Society for Exercise Physiology, the Conference Board of Canada, HALO-CHEO, ParticipACTION and the Public Health Agency of Canada, with input from research experts and stakeholders across Canada and around the world.

The process was informed by 9 peer-reviewed publications, all available for free via the journal of Applied Physiology, Nutrition and Metabolism.

Three papers of particular relevance to sedentary behaviour:

Systematic review of sedentary behaviour and health indicators in school-aged children and youth: an update

Combinations of physical activity, sedentary behaviour and sleep: relationships with health indicators in school-aged children and youth

Associations between sleep duration, sedentary time, physical activity, and health indicators among Canadian children and youth using compositional analyses

Canadian 24-Hour Movement Guidelines for Children and Youth: An Integration of Physical Activity, Sedentary Behaviour, and Sleep

New meta-analysis: the prospective relationship between childhood sedentary behaviour and biomedical health indicators

| June 6, 2016 | 0 Comments

A new paper by van Ekris et al. examines the relationship between childhood sedentary behaviour and health indicators later in life.  From the abstract:

Evidence for adverse health effects of excessive sedentary behaviour in children is predominantly based on cross-sectional studies, measuring TV viewing as proxy for sedentary behaviour. This systematic review and meta-analysis summarizes the evidence on the prospective relationshipbetween childhood sedentary behaviour and biomedical health indicators, overall and stratified by type of sedentary behaviour (TV viewing, computer use/games, screen time and objective sedentary time). PubMed, EMBASE, PsycINFO and Cochrane were systematically searched till January 2015. Methodological quality of all included studies was scored, and a best evidence synthesis was applied. We included 109 studies of which 19 were of high quality. We found moderate-to-strong evidence for a relationship of overall sedentary time with some anthropometrics (overweight/obesity, weight-for-height), one cardiometabolic biomarker (HDL-cholesterol) and some fitness indicators (fitness, being unfit). For other health indicators, we found no convincing evidence because of inconsistent or non-significant findings. The evidence varied by type ofsedentary behaviour. The meta-analysis indicated that each additional baseline hour of TV viewing (β = 0.01, 95%CI = [-0.002; 0.02]) or computer use (β = 0.00, 95%CI = [-0.004; 0.01]) per day was not significantly related with BMI at follow-up. We conclude that the evidence for a prospectiverelationship between childhood sedentary behaviour and biomedical health is in general unconvincing.

The full study is available via Obesity Reviews.

New paper: why are kids failing to meet sedentary behaviour guidelines?

| May 17, 2016 | 0 Comments

 

In May 2014, representatives from 15 countries gathered in Toronto, Canada, for the Global Summit on Physical Activity of Children. Experts reviewed available information and assigned a grade for 9 indicators in national Physical Activity Report Cards. Australia received a grade of “D minus(–)” for sedentary behaviors, with only 29% of 5- to 17-year-olds meeting screen time recommendations. A smaller group from the Australian Report Card Research Working group conducted a study to further review available evidence about sedentary behaviour in children (available here).

They asked the following 3 questions:

Question 1: What are the main sedentary behaviors of children?

Sedentary behavior can occur in 4 areas of children’s lives—education/school/child care, transport, self-care/domestic chores, and leisure/play. For school-aged children, a main “occupation” is being a student and the majority of the school day is spent sitting. Homework also contributes to additional sitting time. Transport time is usually highly sedentary with children sitting in buses, trains and cars to get to and from school and other destinations. Sedentary self-care tasks include eating and some grooming. Leisure and play sedentary behaviors include reading from a book or an electronic screen. Sedentary behaviors are often further classified as being either based around an electronic screen or not.

Question 2: What are the potential mechanisms for sedentary behaviors to impact child health and development?

There are a number of ways by which sedentary behaviors may influence child health and development, including disrupted metabolism, limited neuromuscular activity, prolonged/awkward postures or repetitive motions, socioemotional experiences, cognitive experiences, and other mechanisms such as influencing sleep quality.

Question 3: What are the effects of different types of sedentary behaviors on child health and development?

Research suggests that sedentary behaviors impact child health and development including cardiometabolic, neuromuscular, and psychosocial implications. However, most of the research is about the effects of watching TV, and there has been less of a focus on the effects of total screen time, screens other than TV, non-screen sedentary behaviours, and total sedentary time.

The available research, while incomplete, is sufficiently convincing that sedentary behaviors are important for child health and development. Nations therefore need to balance children’s healthy and unhealthy sedentary behaivours in order to improve their sedentary behaviour grade in future report cards.
